>Description:
sys/types.h only defines u_long etc when _XOPEN_SOURCE is not defined,
however unistd.h has prototypes which use u_long etc when _XOPEN_SOURCE
is defined. This causes compilation errors for any programs which include
unistd.h.
>How-To-Repeat:
Create test.c with thes two lines:
#define _XOPEN_SOURCE 500
#include <unistd.h>
gcc -S test.c
In file included from test.c:2:
/usr/include/unistd.h:140: syntax error before `u_long'
/usr/include/unistd.h:151: syntax error before `fd_set'
/usr/include/unistd.h:177: syntax error before `ualarm'
/usr/include/unistd.h:177: warning: parameter names (without types) in function declaration
/usr/include/unistd.h:177: warning: data definition has no type or storage class
/usr/include/unistd.h:179: warning: parameter names (without types) in function declaration
>Fix:
Probably
#ifndef _POSIX_SOURCE
in unistd.h should become
#if !defined(_POSIX_SOURCE) && !defined(_XOPEN_SOURCE)
but i am unsure of the requirements of the XOPEN standard.
